“…Cost is a primary barrier as all adaptation strategies considered here require investment, in the form of retrofitting (seawater and dry air cooling), increased deployment of alternative energy, or in the revenue lost from retiring plants early. It may be necessary to employ market mechanisms (for example, subsidies, water prices) to encourage these vulnerability-reducing alternatives 20,21 . The second barrier is the fragmentation of energy and water policy frameworks.…”

Climate change and the vulnerability of electricity generation to water stress in the European Union

Thermoelectric generation requires large amounts of water for cooling. Recent warm periods have led to curtailments in generation, highlighting concerns about security of supply. Here we assess EU-wide climate impacts for 1,326 individual thermoelectric plants and 818 water basins in 2020 and 2030. We show that, despite policy goals and a decrease in electricityrelated water withdrawal, the number of regions experiencing some reduction in power availability due to water stress rises from 47 basins to 54 basins between 2014 and 2030, with further plants planned for construction in stressed basins. We examine the reasons for these pressures by including water demand for other uses. The majority of vulnerable basins lie in the Mediterranean region, with further basins in France, Germany and Poland. We investigate four adaptations, finding that increased future seawater cooling eases some pressures. This highlights the need for an integrated, basin-level approach in energy and water policy.T he electricity sector comprises at least 20% of total water withdrawal in most EU nations and approximately 55% on average across the EU 1 . The predominant use is for cooling within thermal power plants and takes place within a few hundred metres of the power plant itself 2 . Water withdrawal places local pressures on the social and ecological environment and is set to develop further under climate change as precipitation patterns change and average ambient temperatures increase [3][4][5] . In recent years, severe water shortages have occurred throughout the EU, for example during the summer droughts of 2003 and 2006, resulting in power curtailments 2 . As periods of water shortages in the EU are projected to increase due to climatic changes, understanding these impacts on the energy system becomes an essential component of EU climate change adaptation and mitigation analysis 6 . The EU has positioned itself as an international leader in the development of climate-energy policy 7 . EU targets for renewable energy, which withdraws negligible water, would be assumed to reduce thermoelectric water stress across the EU into the future 8 . Water use in power production has drawn increasing interest as researchers and policymakers have become aware of the growing sensitivity of the energy system to water availability 9,10 . Research has focused on water footprint analyses, where different approaches have been used to determine the water requirements of energy and fuel production both at the individual plant 2 , and regional level 11 . As the footprint of stationary electricity generation is almost entirely attributed to cooling requirements rather than fuel extraction or refinement 2 , studies have focused on the water footprint of electricity production (WFEP) from the power plants themselves [11][12][13][14] . Connecting these footprints to water availability and temperature is an important next step to providing insight into sensitivities of the electricity system to water resources.

“…The combination of several sources of renewable energy based on local efficiency will be able to replace only part of the energy sources based on fossil fuels. However, after the coal reserves have been exhausted, economic, social and environmental factors will have to be re-evaluated in order to stabilize the economy of the region (Fais, et al, 2014;Arnold, 2015;Menegaki, 2013;Pereira et al, 2014) …”

ABSTRACT:Renewable energy sources are major components of the strategy to reduce harmful emissions and to replace depleting fossil energy resources. Data from remote sensing can provide information for multicriteria analysis for sources of renewable energy. Advanced land cover quantification makes it possible to search for suitable sites. Multicriteria analysis, together with other data, is used to determine the energy potential and socially acceptability of suggested locations. The described case study is focused on an area of surface coal mines in the northwestern region of the Czech Republic, where the impacts of surface mining and reclamation constitute a dominant force in land cover changes. High resolution satellite images represent the main input datasets for identification of suitable sites. Solar mapping, wind predictions, the location of weirs in watersheds, road maps and demographic information complement the data from remote sensing for multicriteria analysis, which is implemented in a geographic information system (GIS). The input spatial datasets for multicriteria analysis in GIS are reclassified to a common scale and processed with raster algebra tools to identify suitable sites for sources of renewable energy. The selection of suitable sites is limited by the CORINE land cover database to mining and agricultural areas. The case study is focused on long term land cover changes in the 1985-2015 period. Multicriteria analysis based on CORINE data shows moderate changes in mapping of suitable sites for utilization of selected sources of renewable energy in 1990, 2000, 2006 and 2012. The results represent map layers showing the energy potential on a scale of a few preference classes (1-7), where the first class is linked to minimum preference and the last class to maximum preference. The attached histograms show the moderate variability of preference classes due to land cover changes caused by mining activities. The results also show a slight increase in the more preferred classes for utilization of sources of renewable energy due to an increase area of reclaimed sites. Using data from remote sensing, such as the multispectral images and the CORINE land cover datasets, can reduce the financial resources currently required for finding and assessing suitable areas.* Corresponding author.

“…They are mostly solved by optimization or simulation techniques when minimizing system costs or maximizing the overall welfare. Fais et al (2014) integrate different types of RES support schemes such as feed-in tariffs as well as quantity based instruments such as certificate systems in their energy system model Times-D. Their approach can be used to analyze exogenous support scheme but does not establish a link between attaining a specific CO 2 target and the level of required RES support, and does not allow analysis of long-term development. Moreover, RES generation is limited exogenously via upper bounds on annual maximum expansion.…”

This paper presents a general electricity-CO 2 (ELCO) modeling framework that is able to simulate interactions of the energy-only market with different forms for national policy measures. We set up a two sector model where players can invest into various types of generation technologies including renewables, nuclear and Carbon Capture, Transport, and Storage (CCTS). For a detailed representation of CCTS we also include industry players (iron and steel as well as cement), and CO 2 transport and CO 2 storage including the option for CO 2 enhanced oil recovery (CO 2 -EOR). The players maximize their expected profits based on variable, fixed and investment costs as well as the price of electricity, CO 2 abatement cost and other incentives, subject to technical and environmental constraints. Demand is inelastic and represented via a selection of type hours. The model framework allows for regional disaggregation and features simplified electricity and CO 2 pipeline networks. The model is balanced via a market clearing for the electricity as well as CO 2 market. The equilibrium solution is subject to constraints on CO 2 emissions and renewable generation share. We apply the model to a case study of the UK Electricity Market Reform to illustrate the mechanisms and potential results attained from the model. Terms of use: Documents in
